| 内容記述 | Background/Aim: 5-Aminolevulinic acid(5-ALA) is a natural amino acid and a precursor of protoporphyrin IX (PpIX). Following light irradiation, the PpIX generates reactive oxygen species (ROS) in the presence of oxygen. Increased ROS levels can cause apoptotic cell death and necrosis of targeted cancer cells. This study examined whether photodynamic therapy using 5ALA (5-ALA PDT) could be used as a potential adjuvant therapy for bone and soft tissue sarcomas. Materials and Methods: The human osteosarcoma (143B), mouse osteosarcoma (LM8), human fibrosarcoma cell (HTl080) cell lines were used. In vitro, cultured cells were exposed to 5-ALA at various concentrations followed by strobe scope light irradiation for 10 min as 5-ALA PDT. Cell viability was then measured. In vivo, each tumour cell line was inoculated subcutaneously into the backs of mice. In the 5-ALA PDT group, 5-ALA (250m g/kg) was administered intraperitoneally followed by light irradiation. Change in tumour volume by 5-ALA PDT were primarily evaluated. Results: In vitro, treatment of sarcoma cells with 100 and 200μg/ml 5-ALA PDT significantly inhibited cell proliferation at 24 and 48h, compared with the group treated with O and 10μg/ml 5-ALA PDT. In vivo, in all cell lines, a significant inhibition of the tumour volume was observed in the 5-ALA-PDT group as compared to that in control, strobe scope light, and 5-ALA groups. Conclusion: 5-ALA PDT effectively inhibited proliferation of bone and soft tissue sarcoma cell lines. Further in vivo research using other subtypes of bone and soft tissue sarcoma is warranted to confirm the applicability in clinical setting. |
